Stopping point

ABSTRACT

Disclosed is a stopping point comprising a connecting eye ( 1 ) used with stopping or lashing means. Said connecting eye is rotatably mounted on an anchoring screw ( 4 ) which is undetachably connected to a supporting disc ( 10 ). The base ( 2 ) of the connecting eye leans against a ring flange ( 13 ) of the anchoring screw ( 4 ) head ( 5 ) via a first series of rolling bodies ( 11 ) and against the supporting disc ( 10 ) via a second series of rolling bodies ( 12 ) so as to ensure high rotatability of the connecting eye ( 1 ) in relation to the anchoring screw ( 4 ).

TECHNICAL FIELD

The invention relates to a point of attachment having a connection eye,into which an attachment or lashing means can be fitted, and ananchoring bolt, which serves for fastening the same on an object and ofwhich the head is provided with an annular flange on which is supportedthe connection eye, which has a base provided with a bore and is mountedin a rotatable manner on the anchoring bolt.

PRIOR ART

A point of attachment of the abovementioned type which is designed as aso-called ring bolt is known from EP 0654611 B1. In the case of theknown point of attachment, a cylindrical section which adjoins theannular flange of the head of the anchoring bolt projects slightlybeyond the underside of the base of the connection eye, with the resultthat the latter can rotate freely about the longitudinal axis of theanchoring bolt. The known solution is distinguished by a simplicitywhich takes account of the mass-produced nature of points of attachment.As the loads which are to be raised by means of relevant points ofattachment increase in weight, it is nevertheless possible, on accountof the frictional conditions between the annular flange and the base ofthe eye, for the automatic alignment of the connection eye in thepulling direction of the attachment means connected to the connectioneye in each case to be impaired.

In order to reduce the frictional forces, in the case of a point ofattachment which is known from DE 43 36 779 C2, a ball-mountedconnection eye is supported in relation to a bushing-like carrier whichis retained by an anchoring bolt of standard dimensions. This secondknown solution is not fully satisfactory because, with it, the distancebetween the connection eye and the load is comparatively large and, inthe case of forces acting more or less obliquely on the connection eye,the tilting resistance of the connection eye leaves something to bedesired.

DESCRIPTION OF THE INVENTION

The object of the invention, in the case of a point of attachment of thegeneric type, is for the rotatability of the connection eye to beensured even when heavy loads are handled. Attempts are madesimultaneously for the connection-eye tilting resistance, which isalready high in any case on account of the proximity of the base of theconnection eye to the load, to be increased further, in the case offorces being introduced obliquely, by a particularly expedientarrangement and selection of the rolling-contact bearings. This objectis achieved according to the invention in that, in the case of a pointof attachment of the generic type, a supporting disk is connected incaptive fashion to the anchoring bolt, and in that the base of theconnection eye is supported, via a first series of rolling-contactbodies, against the annular flange of the head and, via a second seriesof rolling-contact bodies, against the supporting disk.

It is not just the case that the already indicated disadvantages of theknown design described above are eliminated in the case of the point ofattachment according to the invention; in addition, the arrangement ofthe rolling-contact bearings proves to be extremely easy to installsince there is no need for the rolling-contact bodies to be supplied byway of special supply channels.

Further advantages and details of the invention can be gathered from thesubclaims and from the following description of an embodiment of theinvention which is illustrated in the attached drawing.

BRIEF DESCRIPTION OF THE DRAWINGS

In the drawings:

FIG. 1 shows, partly in section, a first view of a point of attachmentdesigned as a ring bolt, and

FIG. 2 shows a second view of the point of attachment according to FIG.1.

METHODS OF IMPLEMENTING THE INVENTION

In FIG. 1, 1 is the connection eye of a point of attachment designed asa ring bolt. The connection eye 1 has a base 2 which is provided with abore 3 for accommodating an anchoring bolt 4. The anchoring bolt 4 has ahead 5 which is provided with a hexagon socket 6. The head 5 of theanchoring bolt 4 is adjoined by a first cylindrical section 7 which, viaa narrow annular collar 8, merges into a second cylindrical section 9,of which the diameter is smaller than the diameter of the firstcylindrical section 7. An annular supporting disk 10 is pressed onto thecylindrical section 9 and the bottom end of the cylindrical section 7and, in the installed state of the point of attachment, is pressedagainst an abutment surface by the anchoring bolt 4.

In order to ensure a high level of rotatability of the connection eye 1even in the event of it being subjected to large forces, the point ofattachment is provided with two series of rolling-contact bodies 11, 12which are formed by grooved ball bearings and of which the series ofrolling-contact bodies 11 is arranged between an annular flange 13 ofthe head 5 of the anchoring bolt 4 and the base 2 of the connection eye1 and the series of rolling-contact bodies 12 is arranged between theunderside of the base 2 of the connection eye 1 and the supporting disk10. It is beneficial for the tilting resistance of the connection eye 1if the diameter of the series of rolling-contact bodies 12 is largerthan the diameter of the series of rolling-contact bodies 11. A steppedbore 14 in the supporting disk 10 forms an additional security againstaxial displacements between the anchoring bolt 4 and the supporting disk10.
